Castilla Thermal Power Station, Chile


The Castilla project was initiated by MPX/E.ON, a joint Brazilian-German venture aiming to construct one of the biggest and most polluting thermal power stations in Latin America. The project also involves the development of an associated port to supply fuel (coal and diesel) for the operation of the thermal power station. Planned for northern Chile, the plant aimed to supply energy mainly to the mining industry. Both projects requested environmental permits separately and several irregularities and pressures from the government in the approval process of the Environmental Impact Assessment (EIA) of the projects were denounced. Local farmers, fishermen, EJOs and congressmen actively opposed the project because of the negative impacts it would bring for health and the environment. Legal measures were undertaken and the Supreme Court unanimously ruled against the Castilla project, stating the port and the thermal power plant needed to be evaluated together, and reaffirming the constitutional right to live in an environment free of pollution.

Project Details and Actors

Project details

The thermal power station would have produced 2354 MW of energy.

More than 21 million m3 of ash would have accumulated over 20 years.

More than 280,000 m3/h of sea water would have been extracted and a large proportion returned with a temperature 10oC higher.

More than 1,300,000 m3/h of greenhouse gases would have been introduced to the atmosphere.

Environmental ImpactsPotential: Air pollution, Biodiversity loss (wildlife, agro-diversity), Food insecurity (crop damage), Global warming, Loss of landscape/aesthetic degradation, Noise pollution, Soil contamination, Waste overflow, Oil spills, Surface water pollution / Decreasing water (physico-chemical, biological) quality, Groundwater pollution or depletion
Health ImpactsPotential: Exposure to unknown or uncertain complex risks (radiation, etc…), Mental problems including stress, depression and suicide, Other environmental related diseases
Other Health impactsHealth impacts due to air pollution
Socio-economical ImpactsPotential: Increase in Corruption/Co-optation of different actors, Displacement, Loss of livelihood, Loss of traditional knowledge/practices/cultures, Violations of human rights, Loss of landscape/sense of place


Project StatusStopped
Conflict outcome / response:Court decision (victory for environmental justice)
Strengthening of participation
Project cancelled
Do you consider this an environmental justice success? Was environmental justice served?:Yes
Briefly explain:After several social mobilizations and the use of legal avenues, the project was stopped by the Supreme Court. This case is emblematic for several reasons, as the ruling prioritised the precautionary principle, making a decision before damage could be caused by the industry, and deciding for the first time in favour of the constitutional right to live in an environment free of pollution.
